We aimed to describe the characteristics and care of participants with diabetes during Ramadan in the Middle East and North Africa (MENA). Methods: In this prospective, observational study, we analysed the number of fasted days, number of participants fasting, glycemic control, rate of hypoglycemic events, and lifestyle patterns for participants with T2DM during Ramadan 2016. Results: The population included 1749 participants with T2DM. The mean (SD) duration of fasting was 27.7 (5.0) days, and 57.3% of participants fasted for the full duration of Ramadan. Following Ramadan, a significant improvement in HbA1c, FPG, and PPG was observed (p < 0.0001). Confirmed hypoglycemia increased significantly from before to during Ramadan (incidence: 4.9% vs. 10.4%, p < 0.001; adverse events: 0.11 vs. 0.22 events/month/participant, p < 0.001) and was dependent on the treatment regimen. Severe hypoglycemia incidence was 0.2% before versus 0.9% during Ramadan (p = 0.031), whereas adverse events

Dexfenfluramine and fenfluramine greatly increase the risk of developing pulmonary hypertension (PHT). The mechanism of anorexigen-associated PHT (AA-PHT) and the reason PHT occurs in a minority of people exposed are unknown. Anorexigens are weak pulmonary vasoconstrictors, but they become potent when synthesis of the endogenous vasodilator nitric oxide (NO) is suppressed. We hypothesized NO deficiency predisposes affected individuals to develop AA-PHT. A prospective, case-control, study was performed on consecutive patients with AA-PHT (n = 9). Two sex-matched control groups were selected: patients with primary PHT (P-PHT, n = 8) and normal volunteers (n = 12). Lung NO production (VNO) and systemic plasma oxidation products of NO (NOx) were measured at rest and during exercise. AA-PHT developed 17 +/- 6 mo after a short course of anorexigen (6 +/- 2 mo) and was irreversible. VNO was lower in AA-PHT than in P-PHT and correlated inversely with PVR (p < 0.05). The apparent VNO deficiency may have resulted from increased oxidative inactivation of NO in patients with AA-PHT, as their NOx levels were elevated (p < 0.05) in inverse proportion to VNO (r2 = 0. 55; p < 0.02). In susceptible persons, anorexigens can cause an irreversible syndrome of PHT, hypoxemia, and systemic vascular complications after brief exposures. These patients have a relative NO deficiency years after discontinuing the anorexigen, perhaps explaining their original susceptibility.

ObjectiveThe American Diabetes Association and the European Association for the Study of Diabetes guidelines recommend to individualize treatment targets/strategies in inadequately controlled patients by lifestyle management and glucose-lowering drugs to decrease the burden of diabetes-related complications. This real-world practice study aimed to assess predictive factors for achieving the glycemic hemoglobin A1c (HbA1c) at 6 months as targeted by the treating physician in adults with type 2 diabetes who required initiation of basal insulin, initiation of bolus insulin, or modification from basal or premixed insulin to new insulin regimen containing insulin glargine and/or insulin glulisine.Research design and methodsThis was an international, multicenter, observational survey with 12-month follow-up time in adults with type 2 diabetes inadequately controlled conducted in 10 developing countries.ResultsOverall, 2704 patients (mean age: 54.6 years, body mass index: 28.7 kg/m2; Caucasian: 46.1%, type 2 diabetes duration: 10.1 years) with poor glycemic control (mean HbA1c: 9.7% (83 mmol/mol), fasting blood glucose: 196.8 mg/dL) were eligible. At 6 months, advanced age, Caucasian ethnicity, shorter type 2 diabetes duration (>10 vs 1 year, p<0.0001), lower baseline HbA1c (≥ 8.5% vs <7%, p<0.0001) and no intake of oral antidiabetic drug (OAD) (none vs 2, p=0.02) were predictive factors for achieving glycemic goal as targeted by the treating physician. Absolute changes in the mean HbA1c of −1.7% and −2% were observed from baseline to 6 and 12 months, respectively.ConclusionsAlong with some well-known predictive factors, this study suggested that early insulin regimen treatment initiation and/or intensification allowed patients to promote glycemic control.
